I'm not entirely sure 64-bit is the issue. I installed the 32-bit version of Kubuntu 11.04 onto the same machine as my previous message and I got similar results -- i.e., Rakudo with 3.3 is slower than Rakudo with 3.0 even in a 32-bit environment: Dell Dimension 9150, 4GB RAM, 32-bit, Kubuntu 11.04 i386 Version T1 T2 T3 T4 Fastest vs 2011.01 -------------------------------------------------------------------------- rakbench-01 (core.pm): 2011.01/3.0 (ms2) 166 169 168 170 166 100.0% 2011.02/3.1 (ms2) 306 305 306 306 305 183.7% 2011.03/3.2 (gms) 196 197 197 197 196 118.1% 2011.04/3.3 (gms) 205 205 206 205 205 123.5% Full results and logs are available at https://github.com/pmichaud/rakbench . Also, my 64-bit laptop (HP EliteBook 2530p, 3GB RAM, 64-bit) shows results more like what you were originally reporting -- i.e., 3.3 is faster than 3.0. HP EliteBook 2530p, 3GB RAM, 64-bit, Kubuntu 11.04 amd64 Version T1 T2 T3 T4 Fastest vs 2011.01 -------------------------------------------------------------------------- rakbench-01 (core.pm): 2011.01/3.0 (ms2) 179 178 172 173 172 100.0% 2011.02/3.1 (ms2) 194 194 194 194 194 112.8% 2011.03/3.2 (gms) 132 132 131 132 131 76.1% 2011.04/3.3 (gms) 143 141 142 143 141 82.0% I'm currently re-running the suite on my desktop with 64-bit to make its statistics and logs completely consistent with the new rakbench scripts I'm using. After that's done, I'll re-run the suite on my desktop but limit the kernel to only 3GB of memory (instead of 4GB), to see if that makes a significant difference.
